In Ableton I add the loop, hook, and percussion tracks and have eached routed to a different return track. I label each song section, add guides and dynamic guides, and click and tempo. From there, I add repeats and locators for each section. I have locators labelled  for a liobox and repeats mapped to the key “r” to be able to repeat a section on the fly during a service. If we go to a new section or something spontaneous, I have each return set with a cut off filter and mapped to faders to bring tracks or parts in and out.
